AI Invoice Processor — Automated Invoice Parsing & Extraction
An AI-powered invoice processing system that automatically detects, extracts, and stores structured data from uploaded invoices — using OCR and LLM to handle any format, vendor, or layout with zero manual data entry.

01 / Project Overview
What We Built & Why
AI Invoice Processor is a fully automated invoice data extraction platform that monitors a designated folder (local system or Google Drive) for new invoices and processes them instantly. Using a combination of OCR and LLM-powered parsing, it extracts key fields — vendor name, amount, tax, due date, invoice number — and stores structured data in a database.
The system handles invoices in PDF, PNG, JPG, and JPEG formats regardless of layout or vendor — eliminating hours of manual data entry and ensuring 100% consistent, structured records every time.
Core problem solved: Finance teams spend hours manually re-typing invoice data from PDFs and images into spreadsheets or ERP systems. This platform reduces that to zero manual work — every invoice is parsed, summarised, and stored automatically within seconds of upload.
Any Format
Handles PDF, PNG, JPG, JPEG — regardless of vendor layout or design.
Smart Extraction
Vendor, amount, tax, due date, invoice number extracted automatically.
File Monitoring
Watches folder 24/7 — triggers processing the moment a new file appears.
Database Storage
Parsed data stored in structured DB — ready for querying and analysis.
Live Application
Invoice Processing System — Dashboard
What you see
Drag & Drop Upload + Live Stats
The dashboard shows real-time invoice stats — 105 total invoices, 0 processed (pending batch), 33 pending. Users drag & drop any invoice file and the system processes it automatically.

02 / How It Works
The Automated Invoice Pipeline
From file detection to structured database storage — every step is fully automated. No manual trigger, no human review required.
System watches the designated folder (local or Google Drive) 24/7 and detects any newly uploaded invoice file instantly.
PDF, PNG, JPG, or JPEG invoice file detected and loaded into the processing pipeline automatically.
Optical Character Recognition converts invoice images and PDFs into machine-readable text — capturing all visible fields.
LLM (OpenAI) intelligently parses the raw OCR text — identifying and extracting vendor, amount, tax, date, and invoice number.
Structured summary of the extracted data created — all key fields captured in a clean, consistent format.
Parsed invoice data and summaries stored in the database (SQL/NoSQL) — fully indexed for fast retrieval and analysis.
Processed invoice data exported to Excel automatically — ready for finance teams to download and use immediately.
Invoice fully processed — zero manual input, zero data entry. Dashboard stats updated in real time.
